jquery - Php page working by oneself but I cant get result of php page with ajax as dynamically

Solution:

would be nice to get more information where your code fails: in PHP or in ajax, do your get data in PHP or don't even reach PHP code. Did you checked are you getting your 'catid='+val value in PHP code? I would recommend console.log(data) in success function.

• var_dump($_POST);
• F12 -> network -> find your get-values.php

Also i would suggest:

var param = "catid"+val

data: {catid: param} Then in PHP you will get $_POST['catid']

Solution:

Actually problem is only select> tag.Code page working by oneself but i cant show result inside of div> tag.

php file

  {-code-2}

---After to other selections i should show category attribute names and values.First loop for gather attribute names.This loop creating tags.Inside of this loop i have secondary loop for gather attribute values.Below echo giving that result to me as fine.-----

echo "<option value=".$attlistid.">".$attlistname."</option>";

script

function GetCatVal(val) {
    $.ajax({
        type: "POST",
    url: "./php/get-values.php",
    data:'catid='+val,

    success: function(data){
        $("#katvallist").html(data);

    }
});
}

If i try change some php code for show results inside of select tag its working fine.I can show result to select id="katvallist"> with only creating options> in php codes. but i cant show any data inside of div id="katvallist"> tag.
